What is the INCI?
In the cosmetic industry, the compounds on the ingredient list are determined by the PCPC and published in a book called the International Nomenclature of Cosmetic Ingredients (INCI).
The INCI Directory is a great free resource that lists fairly accurate information about the INCI. Here is a video which describes how to use it.
Note: This is not an official production of the PCPC so you should not use the information found in the INCI Directory without verifying it’s accuracy with the PCPC.
